Definitions

  • the disclosure relates to a sealing arrangement of a wheel bearing.
  • wheel bearings of motor vehicles require double-sided sealings of the interior which are filled with lubricant and which contain the rolling bodies.
  • centrifugal sheets are used, which form a sealing labyrinth along with the sealing lips.
  • a sealed bearing arrangement is known from the DE 10 2010 055 178.
  • the bearing arrangement features a sealing arrangement on both sides of the axial ends.
  • This sealing arrangement consists of a sealing ring, features several apertures that are distributed along the circumference, which are sealed in a semipermeable manner by using a elastomer diaphragm and which form a gas channel.
  • this task is accomplished by using a sealing arrangement of a wheel bearing with a first bearing part and with a second bearing part that is connected in one piece with a wheel bearing flange, between which rolling bodies are guided, wherein the sealing arrangement comprises the following:
  • a carrier element which is connected to one of the two bearing parts and wherein an elastic element is provided on the carrier element, wherein the elastic element features at least one sealing lip,
  • a cavity is configured between the first bearing part and the second bearing part, which cavity is delimited by using the carrier element and/or the elastic element, and
  • the carrier element and/or the elastic element feature at least one aperture at the radial level of the cavity, and wherein the at least one aperture is sealed by way of a diaphragm, and wherein the diaphragm is connected directly and/or indirectly to the carrier element, wherein at least one protective lip is provided on the opposite side of the diaphragm, and wherein the a least one protective lip is formed at the elastic element and/or at the carrier element.
  • the sealing arrangement features a diaphragm, which is connected directly and/or indirectly to the carrier element and which seals the at least one aperture.
  • at least one protective lip is provided at the carrier element.
  • This protective lip may be made of an elastomer.
  • the protective lip is hereby either directly connected to the carrier element or the protective lip is formed by using the elastic element, which already forms the sealing lip.
  • the purpose of the protective lip is to protect the diaphragm against contamination such a grease, oil, water and the like.
  • two protective lips are intended, which are approximately arranged in a V-shape formation, in order to form a narrow gap. This narrow gap further ensures the function of the diaphragm and thereby the ventilation for a pressure equalization when temperature differences occur.
  • the at least one aperture that is provided in the carrier element can be designed as a bore hole, slot, or the like. If the carrier element features several apertures, these are arranged in a distributed manner along the circumference.
  • the apertures can be provided e.g. in an evenly distributed manner and/or with a radial offset towards each other.
  • the carrier element can be formed in an L-, C- or S-shape. It may also be possible that the carrier element does not feature at least one sealing lip, but that it serves as a stop face for at least one sealing lip.
  • the at least one protective lip is formed by using the elastic element.
  • the protective lip can be additionally formed on the carrier element in one manufacturing step when the elastic element is applied, which in turn forms the at least one sealing lip. A separate manufacturing step would thus be avoided. Overall, a simple and cost-effective production is thus provided and ensured.
  • an air volume is provided between the diaphragm and the carrier element.
  • the air volume may be created by using a depression provided on the carrier element.
  • the depression may be chamfered or the like.
  • Such an embodiment of the disclosure serves to increase the active surfaces of the diaphragm. This has the result, that a larger portion of the surface of the diaphragm can be used for the ventilation.
  • the at least one aperture is drilled, punched, milled and/or lasered.
  • the carrier element may be manufactured out of a metal or plastic material. The stiffness of the sealing arrangement is thus ensured.
  • FIG. 1 a section from a sealing arrangement of a wheel bearing in line with the disclosure according to a first embodiment
  • FIG. 2 a section from a sealing arrangement of a wheel bearing in line with the disclosure according to a second embodiment.
  • FIG. 1 depicts a section of a sealing arrangement 1 according to the disclosure of a wheel bearing that is not shown in detail in accordance with a first embodiment.
  • the sealing arrangement 1 comprises a carrier element 2 , which is formed in an L-shape and which features a first section 7 and a second section 8 .
  • carrier element 2 is connected to one of the bearing parts of the wheel bearing that are not shown in detail.
  • An elastic element 3 is connected to carrier element 2 .
  • the elastic element 3 features three sealing lips 4 , 5 , 6 in this embodiment. These sealing lips 4 , 5 , 6 either lie against a further metal sheet or at one of the two bearing parts of the wheel bearing.
  • Second section 8 of carrier element 2 features at least one aperture 9 . It is formed as a bore hole 10 with a constant diameter. Aperture 9 is sealed on one side of the second section by using a diaphragm 11 . Diaphragm 11 is hereby directly connected to carrier element 2 . The second section 8 features a depression 12 in the region of diaphragm 11 , which creates an air volume between diaphragm 11 and carrier element 2 . This causes an increase in the active surfaces of diaphragm 11 .
  • Two protective lips 13 , 14 surrounding the aperture are provided on the opposite side of diaphragm 11 .
  • the two protective lips 13 , 14 are formed by using the elastic element 3 and are thus connected to the second section 8 of the carrier element.
  • the protective lips 13 , 14 run towards each other in a V-shape and thereby form a narrow gap in the direction of aperture 9 . Such an arrangement ensures that diaphragm 11 is protected against contamination such as bearing oil or grease.
  • FIG. 2 Identical components are referred to by the same reference signs as in the preceding FIG. 1 .
  • the description of FIG. 2 is thus limited to components that are different.
  • FIG. 2 depicts a section of a sealing arrangement 1 according to the disclosure of a wheel bearing that is not shown in detail.
  • aperture 9 is implemented in a different way.
  • Aperture 9 is created by use of a bore hole 15 with a chamfer 16 .
  • the diameter of bore hole 15 may increase in the direction of diaphragm 11 . This causes an increase of the active surface of diaphragm 11 .
